Next Gen Power

[alexkyriak]

So what with the 4000 series GPU cards coming up, and the 13/14 series intel K CPUs, the potential power draw of these systems will likely be immense.

Surely at some point, this is going to start becoming prohibitive and costly, both in terms of pure energy consumption, and in components and kit required to enable this generation of CPUs and GPUs, be it in the form of power supplies, cooling systems, etc

At what point will a different approach to computing power need to be implemented? Ie, will there need to be a return to some form of parallel computing power, in the manner of SLI and dual or quad CPUs? Presumably CPUs can’t just keep raising the ghz, and GPUs can’t just consume more and more power in the same single unit. What will a PC in three to five years look like?

Whilst the roadmap looks genuinely exciting, some of the figures being quoted seem a bit mind boggling

there will be a 175w GPU and a 65w CPU so if people are that bothered then they can just get those.

the people mostly affected will be the ones buying the £800+ cards and £400+ cpu`s

Nobody forces you to buy the absolute top end parts.

The top end parts are pushed outside of their efficiency curve in search of extra performance (by feeding them more power) - step down a couple of models and the power consumption performance/watt is normally far better.

Yep fully appreciate no one forces you to buy anything, and that stepping down from the top top end is more efficient. Am interested in this from the top end perspective I guess. The brands and manufacturers push themselves to compete with their competitors for the top spot, and a certain segment of consumers will always go top end to enjoy the most cutting edge technology and games technology.

But that trajectory is looking like it’s going to get harder and harder to achieve, so interested to understand how that will play out and if / when it’ll necessitate some form of step change in the approach.

We already have 2000w psu's the power delivery will be shared over multiple rails I presume.
